TANK-REGISTERING DEVICE.

Specification of Letters Patent.

Patented Apr. 11, 1922.

Application filed February 11, 1918. Serial No. 216,638.

-which the following isa specification.

This invention relates to a tank reg1ster-- ing device, which is adapted to register the quantity of fluid charged into a tank. It contains means for registering equal volumes for variable differences of depths of 'a fluid in a tank, with a round or curved bottom. The invention can be modified to register equal volumes of fluid for equal difierences of the levels of a float ina tank.

Flg. 3 represents an end view of the invention on a-reduced scale with its accompanying tank; Fig. shows a partial section of Fig. 1 on the hne 4.4 with a sectional portion of the accompanying tank; Fig. 5 represents a' partial top plan view and section of Fig.2 on the hne 55; Fig. 6 is a partial sectlon as on the line 6-6 of Fig. 4; Fi 7 shows a rlght hand view of some of t e elements shown in Fig. 4 and Fig. 8 shows a top plan View of a modified detail.

A tank, and in this instance, of an auto mobile is indicated at20 with the opening.

21 and upon which is mounted the casing of the registering device indicated in its entirety by the letter A. The said casing com prises the foot flange 22 with an extension 23. Screws 24 fasten the footflange 22 to the tank 20. The foot flange 22 has extending therefrom the inlet nozzle 25 threaded at 26 for the cap 27. A vertical guide slot 29 is formed in the wall of the nozzle 25. A

lug 30 extends down from the foot flange 22 and has formed therein a cavity 31 and guide opening 32. Through the guide opening 32 and cavity, 31 extends the indicator each endand gradually decreasing toward the center of the sector. This variationof the pitch of the'teeth of the sector provides compensating means for the quantity of fluid, like gasoline at different depths of a tank which is circular or elliptical in crosssection. The sector B hasformed therewith the sleeves 38 which is slidably located on the spindle 3.5. Slots 39 are formed in the sleeve 38, and a pin 40 supported in the spindle 35 extends through the slots 39. A disconnecting bar 44 with foot 45 at right angles-thereto is slidably guided in the guide slot 29, and the foot 45 has an opening 43, which engages thespindle' 35. The foot 45 is supported upon the'top edge of the sleeve 38. A spring 46 is located'in the cavity 31, encircles the spindle 35 and bears between the bottom of said cavity and the bottom face of the sector B. A hood 48 for the sector B is supported on posts .49 that extend up from the foot flange 22. A main registering device of the cylinder type is shown withfive numbered cylinders D, with the casing 50 having the foot 51. The latter is fastened to extension 23 by means of the screws .52. The cylinder D. of the lowest order is actuated by a double arm similar to 71 and spring pawls similar to 72-and '7 3, and the cylinders Dof the higher order are actuated by transfer mechanism not shown.- The arm 71 and pawls 72. and 73 will be described hereinafter. A star wheel 54 has thereon, in this instance, ten teeth I ing 62 and the flange 63. The latter is fastened to the foot 51 by means of the screws,

64. A glass 65 is located in,.the said casing 62. As indicated in the drawings, one end of the casing 62 abuts against its acoompanying end of the casing 50. A supplemental cylinder 67 with numerals on its outer surface has formed therewith the sleeve 68 y with the hand'wheel 69 which are rotatablysupported on the spindle v53. The cylinder f 67 has formed on the inner surface thereof the teeth 70. A double arm 71 is fastened to ders D 69 is turned in a direction opposite to the the spindle 53 and has extending therefrom the spring pawls 72 and 73 which engage the teeth 70. A casing to protect the indicator 36 and the wheel 54 with their appurtenances is shown with the end wall 75, the side walls 76 with the flanges 77 and the top wall 78. In the wall 78 is formed an opening 79 with the glass 80 below the same". A scale E is formed on the top face of the wall 78 for the pointer 36. Screws 83 fasten the flanges 77 to the outer surface of the nozzle 25 and screws 84 fasten the walls 76 to the foot flange 22.

A supporting bar 87 has its upper end fastened to the lug 30, by means of the screws 88 and at its lower end has formed therewith the lug 89. A bevel pinion 90 is fastened to the lower end of the spindle 35 and meshes with the bevel gear 91. The latter has formed therewith the barrel 92. A screw 93 has formed therewith the journal pin 94, and on the latter is rotatably supported the bevel gear 91 and its barrel 92. An arm 95 has one end fastened to the barrel 92 and to its other end is fastened the ball float 96.

To use the device, the operator turns the hand wheel 69 in either direction until 0 is indicated on the cylinder 67 through the glass 65. It will be noted that the hand wheel 69 has a direct mechanical connection with the c linder 67. The spindle 53 has a direct mechanical connection with the awls 72 and 73 and to similar pawls not s own of the cylinder D of the lowest order. Transfer mechanism not shown connect the cylinders D. Therefore, when the hand wheel 69 is turned in the direction of the arrow F, the cylinder 67 slips over the pawls 72 and 73. The spindle 53 at the same time remains at rest and consequently the cylindo not turn. When the hand wheel direction of the arrow F, the cylinder 67 engages the pawls 72, 73 and thereby the spin dle 53 is turned and the pawls in the cylinder D of the lowest order slip over the teeth of the latter. Consequently the cylinders D do not turn with eith r direction of rotation of the wheel 69. VWhen the spindle 53 is turned through the star wheel 54 in the direction of the arrow F, the cylinders D and 67 both turn and register. When the spindle 53 turns in a direction opposite to the arrow F, by means of the star wheel 54, then all the pawls slip. Therefore the amount indicated on the main counter can not be increased or decreased except by the rise of the float 96.

The cap 27 is removed fromthe nozzle 25 and the spring 46 forces up the sector B and with it the disconnecting rod 44, which causes the teeth C of the sector B to mesh with the teeth 55 of the star wheel 54. The pointer 36 is automatically located opposite the numerals on the scale E to indicate the quantity of gasoline or other fluid in the tank 20 through the medium of the gear connections above described. The gasoline or other fluid, is next poured into the tank through the nozzle 25 and the float 96 will thereby rise with the rise of the fluid in the tank. the bevel gear 91 turns on the journal pin 94. The bevel pinion 90 turns with the gear 91 and thereby the spindle 35 turns, which causes the sector B to swing. The movements of the sector B through its teeth C cause the wheel 54 to turn, and thereby the cylinders D of the main counter are actuated in the usual manner and their nu merals indicate the total quantity of gasoline introduced into the tank 20. The supplemental cylinder 67 also turns and indicates through the glass the quantity of.

fluid introduced into the tank at that filling. To fill the tank to one quarter of its capacity it must rise to a level of a line indicated at G-G which is more distant from the bottom of the tank than from its center line H, H. To fill the tank to three fourths its capacity it must be filled to about the line II, which-is a greater distance from the top of the tank than from its center line H H. To compensate for this inequality of levels for equal volumes of the tank, the

teeth C of the sector B are made of greater pitch at their ends than at the center of the sector. By this means a proper amount of rotation is imparted to the cylinders D of the main counter and cylinder 67 of the suplemental counter as the tank is filled. hen the cap 27 is screweddown on its inlet nozzle 25, the adjusting bar 44 is forced downwardly, and thereby the sector B is disconnected from the star wheel 54 and allows the fluid to be drawn from the tank 20 without causing either of the counters to register, and permits the float to move with any variations of the level of the fluid in the tank 20 without the counters registering.

The invention may be modified by substituting for the sector B having the teeth C of variable pitch, a sector with teeth having a uniform pitch. With a sector of uniform pitch the float 96 can be used in a tank with a uniform cross-section.

In Fig. 8 a sector 100 is shown with teeth 101 of uniform pitch.

Having described my invention what I desire to secure by Letters Patent and claim is: Y

1. The combination of a float for a tank, a registering device, a spindle rotated by the movements of the float, a sector having teeth with a varying pitch on the spindle and a star wheel for the registering device meshing with the teeth of the sector.

2'. The combination of a float for a tank moving with variations of the level of a fluid therein, an inlet nozzle for an opening V'Vith the movement of the float 96 the registering device extending therefron'i and a star wheel fastened to the latter spindle meshing with the teeth of the sector.
